Recently, the research group of Professor Tang Huashen and Associate Professor Feng Anchao of Beijing University of Chemical Technology successfully prepared polyvinyl chloride-polycaprolactone block copolymer (PVC-b-PCL) by reversible addition break chain transfer (RAFT)
polymerization.
This block polymer is a new type of PVC-based macromolecular plasticizer, the plasticizing effect can be comparable to the traditional dioctyl phthalate (DOP), and migration experiments show that this is a plasticizer with non-migration characteristics, which will become a new generation of environmentally friendly PVC-based plasticizer
